Invasion: Home

My sister is coming to visit.
Of course, this is the perfect time to have a fruit fly infestation. It’s my own fault. I need to be more proactive with taking out the garbage.
There is a tendency to not want to take it out until the bag is full. I’m a guy, so I don’t smell anything. But I do notice that there are little bugs floating around my kitchen now.
This will reflect poorly on me.
I am going through a whole cleaning phase right now, to prepare for her visit. I was about to start the vacuuming, when I got a call. Apparently, because I answered a survey last month, I’ve won a free gift. Some Ginsu knives. All I have to do is let them demonstrate a vacuum cleaner. Convenient timing.
Or this might be an elaborate ploy to get access to my home while armed with knives.

Could someone check up on me in an hour?
